Tyvek庐 Converting Guide
What technologies are suitable for processing Tyvek庐?
足球价值投注鈩 Tyvek庐 is a non-woven material made of 100% high density polyethylene 铿乥er that integrates the excellent characteristics of paper, cloth and 铿乴m. The processing feasibility same as paper, cloth and 铿乴m endows it with wider application possibilities in printing, packaging, design and consumer goods related 铿乪lds.
Unlike traditional printing substrate paper, Tyvek庐 is a material of a melting point of 135 掳C, water-resistant and non-absorbent, which requires proper adjustment of parameters during certain processing. The following quick reference for processing Tyvek庐 is based on our current knowledge and will be subject to continuous updating.
Coating
The purpose of coating on Tyvek庐 materials is usually to achieve properties/tactility (e.g. PU coating), printability/convertibility (e.g. primer coating for water-based/eco-solvent based inkjet printing or heat-sealing coating), or to improve the performance of printing ink (e.g. primer for Latex, Indigo), etc.
Laminating
Laminating is a common processing technique in Tyvek庐 applications. Tyvek庐 can be laminated with various materials (such as paper, 铿乴m, non-woven fabric and woven fabrics), different adhesives are considered for different substrates.
Gluing
Tyvek庐 has been widely used in printing and packaging, such as envelopes, notebooks, packaging bags and boxes, handbags, etc. and gluing technology is used on Tyvek庐 more and more. Tyvek庐 looks like paper but with quite different properties. During the gluing process, air bubbles and wrinkles are easily caused by improper glue selection or gluing methods. Tyvek庐 is a non-woven material made of high-density polyethylene and can also be classi铿乪d as plastic. Moreover, Tyvek庐 does has unique thickness uniformity unlike typical paper. Therefore, in glue formulation selection, suitability reference should be made to plastic substrates. Water- based or solvent-based or hot-melt adhesive and animal glue can all be used on Tyvek庐. 听
Note: Like gluing other materials, the characteristics of the substrate, the end use conditions and requirements etc. need to be fully acquainted before selecting glue. In addition, it is recommended to communicate with the glue vendor to select the appropriate glue formulation. Evaluation should be conducted before mass production.
Sewing
Tyvek庐 is more and more popular in consumer goods and sewing becomes the most common assemble method to Tyvek. As we mentioned previously, Tyvek庐 is a non-woven material and unlike woven fabric, the needle holes will not disappear after sewing. Therefore, it is recommended to choose smaller needles (e.g. No.10 needles) and not to sew too densely to avoid strength loss. In addition, Tyvek庐 has a smooth surface and is slippery in sewing. It is suggested to replace metal presser foot with plastic one to increase the friction coef铿乧ient.
